Rare Metals, EarlyView.ABSTRACT Internal oxidation has been identified as an effective method for enhancing the strength of AgMg alloys. However, the concurrent occurrence of embrittlement remains inadequately understood, thus limiting their broader application. This study investigates the oxidation behavior of AgMg alloys with Mg concentrations ranging from 1 at% to 7 at ...

Rare Metals, EarlyView.ABSTRACT The transformative potential of gallium nitride high electron mobility transistors (GaN HEMTs) in advancing carbon‐neutral power systems remains bottlenecked by contact resistance (Rc) at the metal–semiconductor (M‐S) interface, a critical determinant of switching losses and frequency response.

Rare Metals, EarlyView.ABSTRACT This study elucidates the oxidation mechanisms governing Y/Hf‐doped AlCoCrFeNiTi high‐entropy alloys (HEAs) and reveals the pivotal role of fabrication processes in dictating high‐temperature oxidation behavior. We demonstrate that casting and spark plasma sintering (SPS) promote Y/Hf segregation, resulting in heterogeneous oxide formation and

Rare Metals, EarlyView.ABSTRACT This study developed a FeSiAl@LMPGP composite material to address the demand for low‐frequency electromagnetic absorption. Through controllable heat treatment, FeSiAl particles and PbO nanoparticles self‐assembled into a high‐density Mott–Schottky heterointerface structure, which exhibited a significant built‐in electric field (BIEF) effect ...

The distribution of examples of the Japanese words that express the feelings about "regret" and "envy" [PDF]
, 2009 日本語心情語彙の通時的研究の一環として,日本文学史上の代表的な作品とみられるものを対象に,｢残念｣と｢嫉妬｣の心情を表す和語の用例分布を調査した｡本稿では,その用例分布表を掲示し分布の特徴を指摘した｡この分野の語の出現頻度は,源氏物語を始めとする平安女流文学作品においてとりわけ際だつ｡現代語につながる｢くやむ｣｢妬まし｣は,中世に派生形として出現した語である｡形容詞からの動詞派生語｢～がる｣の用例は,ほとんど｢くち惜し｣と｢妬し ...

Rare Metals, EarlyView.ABSTRACT The high accuracy in surface‐enhanced Raman scattering‐lateral flow immunoassays (SERS–LFIAs) is critical for reliable point‐of‐care testing (POCT) in clinical diagnostics. Conventional approaches are often affected by sampling variability and uneven distribution of immunoprobes, leading to unreliable signal fluctuations.
